Qiagen, Applied Biosystems

Premium
Qiagen this week released three new RNAi related products.
 
The first is the FlexiPlate siRNA, a line of 96-well plates in 0.1 nmol, 0.25 nmol, and 1 nmol scales for use with human or mouse target genes.
 
SiRNAs and controls, Qiagen said, can be selected and arranged on the plates using a Web-based interface.
 
The company has also released the HP OnGuard siRNA design algorithm.
The algorithm incorporates a neural-network algorithm and proprietary homology analysis, in addition to other new features including 3' UTR/seed region analysis, SNP avoidance, and interferon motif avoidance, Qiagen said.
 
Lastly, Qiagen introduced the Human Druggable Genome siRNA set 3.0, which targets more than 7,000 genes of therapeutic value. SiRNAs are available through the set either individually or in pools.
 

 
Applied Biosystems has introduced new TaqMan microRNA assays, including assays for human, mouse, Drosophila, and C. elegans genes.
 
The new assays are in addition to the company’s existing assays for rat and Arabidopsis genes and increase the complete TaqMan miRNA assay collection to 571.
